2.1 Software history

The PROFIBUS DP device has a RS485 interface to connect the device to a PROFIBUS DP
network.

The software supports the PROFIBUS PA Profile 3.02. Both, cyclic services towards a control
system (e.g. PLC) as well as acyclic services for operating with engineering tools (e.g. DD/DTM
based tools) are supported.

The PROFIBUS station address can be set via PROFIBUS services or via the device display.

2.2 System configuration of PROFIBUS DP network

The following diagram shows a typical network configuration with PROFIBUS devices with RS485
interface in a non-hazardous environment. The PROFIBUS devices with RS485 interface do not
need any segment coupler. They are connected directly to the PROFIBUS DP network.
